One-way dense rib cavity floor system module for concrete structure and construction method of one-way dense rib cavity floor system module

Abstract

The invention discloses a one-way dense rib cavity floor system module for a concrete structure and a construction method of the one-way dense rib cavity floor system module, and relates to the technical field of fabricated buildings. The one-way dense rib cavity floor system module for the concrete structure is formed by connecting and prefabricating at least two side dense rib beam half molds, at least one reinforced concrete inner dense rib beam and at least one bottom plate; the side dense rib beam half-molds and the inner dense rib beams are arranged in parallel, and the lower ends of the side dense rib beam half-molds and the lower ends of the inner dense rib beams and the bottom plate are prefabricated into a whole through internal reinforcing bars and concrete; according to the one-way dense rib cavity floor system module for the concrete structure and the construction method of the one-way dense rib cavity floor system module, the construction time can be saved, the number of formwork supporting rods is reduced, the construction period is shortened, and the cost can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a one-way dense rib cavity floor module for concrete structures and a construction method thereof. Background technique [0002] In the reinforced concrete structure, the laminated floor that is widely used at present has a relatively small suitable span and a relatively large self-weight of the floor. The middle thickness will increase, reducing the clear height of the building, which is not conducive to the use of users. [0003] The rib cavity floor system has been widely used in cast-in-place concrete structures and precast concrete structures in recent years. The technical scheme of combining prefabricated cavity components and cast-in-place concrete rib beams to form a concrete rib cavity floor is disclosed, but this is a cast-in-situ rib beam and cast-in-place slab method, which does not belong to prefabricated buildings. ; Another example, the invention ...

AI Technical Summary

Problems solved by technology

[0002] In reinforced concrete structures, laminated floors are widely used. Due to the relatively small span and relatively large floor weight, the amount of wet work on the laminated slabs is also not small. In addition, the floors using this type of laminated slabs The thickness of the medium will increase, reducing the clear height of the building, which is not conducive to the use of users

[0003] The dense rib cavity floor system has been widely used in cast-in-situ concrete structures and precast concrete structures in recent years. Disclosed is a technical scheme in which prefabricated cavity components and cast-in-place concrete ribbed beams are combined to form a concrete ribbed cavity floor, but this is a form of cast-in-site densely ribbed beams and cast-in-place slabs, which does not belong to prefabricated buildings Another example, the invention patent of a two-way densely ribbed cavity floor and its construction method (patent number is ZL201310490037.2) discloses the combination of a steel densely ribbed beam and a prefabricated reinforced concrete slab to form a densely ribbed cavity floor Technical solution, although this type of floor slab and process can be included in the prefabricated building technology, but its construction process is relatively complicated, and there is no reliable connection between the prefabricated floor and the steel beam
